FELLER ATTACHMENT.

Specification of Letters Patent.

Patented May 21, thin.

Application filed November 30, 1917. Serial No. 204,751.

To all whom it may concern:

Be it known that I, ,FRANK THOMPSON, a citizen of the United States, residing at Shawnee, in the county of Pottawatomie and State of Oklahoma, have invented a new and useful Feller Attachment, of which the following is a specification.

The device forming the subject matter of this application is a means whereby a feller may be attached readily to a sewing machine, and with equal facility be detached therefrom, it being a matter of common knowledge that a considerable amount of time is lost in the application and detachment of fellers to and from sewing machines.

The present invention aims to provide a means whereby, through the manipulation of a simple cam lever, a feller carrier may be connected with or disconnected from a support, the construction being such that when the cam lever is in looking or holding position, the necessary security and rigidity will be obtained.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows the invention in top plan;

Fig. 2 is a longitudinal section, wherein the feller has been removed;

Fig. 3 is a perspective showing the feller carrier;

Fig. 4 is a perspective showing the support wherewi-th the feller carrier is adapted to cooperate.

In carrying out the present invention, there is provided a support 1, which may be variously formed, depending upon the make of sewing machine wherewith the device forming the subject matter of this application is used. In the present instance, the

support 1 has been shown in the form of a transversely curved plate provided with an oil hole 2, needle slots 3 and feeder slots 4;. Adjacent one end and upon its upper surface, the support 1 is flattened to form a table 5 in which is fashioned a longitudinal slot 6 defining fingers 7 The feller carrier 8 preferably is in the form of a flat plate adapted to rest on the table 5, the feller carrier being equipped with a depending longitudinal rib 9 carrying an car 10 supporting a pivot element 11.

The numeral 12 indicates a cam lever terminated in a bifurcated head 1t having a slot 15 defining side arms 16, the ear 10 being received in the slot 15 and the ends of the pivot element 11 being mounted in the side arms 16. The terminal edges 17 and 18 of the head 14 of the cam lever are inclined, and the construction is such that, as hereinafter described, a cam effect may be produced when the lever is manipulated properly.

The carrier 8 is equipped with a feller 20 of any desired construction.

In practical operation, the feller carrier 8 is pushed rearwardly along the table 5, the rib 9 entering the slot 6 and cooperating with the fingers 7 to prevent relative lateral movement between the feller carrier 8 and the support 1. If the cam lever 12 be swung downwardly into the position shown in Fig. 3, edges 17 will bear against the under side of the fingers 7 and hold both the feller carrier 8 and the feller 20 against movement. When, however, the lever 12 is swung upwardly so that the edges 18 lie parallel to the under face of the table 8, then the feller carrier and the feller may he slipped readily off the support '1.

Having thus described the invention, what is claimed is 1. In a sewing machine attachment, a sup port provided with a slot in one end; a feller carrier having a rib received in the slot; a feller on the feller carrier; and a clamping device mounted on the rib and coacting with the under surface of the support.

a feller carrier slot; a cam lev 5 acting with th slot; and a fel having a rib received in the er pivoted to the rib and c0- e support at the side of the ler 0n the feller carrier.

In testimony that I claim the foregoing Copies of this patent may be obtained for five cents each, by addressin as my own, I have hereto aflixed my signature in the presence of two Witnesses.

FRANK THOMPSON.
